melonDS aims at providing fast and accurate Nintendo DS emulation. While it is still a work in progress, it has a pretty solid set of features.

  • Nearly complete core (CPU, video, audio, ...)
  • OpenGL renderer, 3D upscaling
  • RTC, microphone, lid close/open
  • Joystick support
  • Savestates
  • Various display position/sizing/rotations modes
  • Work-in-progress Wi-Fi emulation for online connectivity and local multiplayer
  • Experimental emulation of the Nintendo DSi
  • ...and even more is planned!
